Management Scientists or researchers: develop management theories which guide the managers to become more organized and structured in their policies and procedures. They are expected to utilize scientific methodology, sociology for organizational decisions as well as people management.Managers: manage the operations and employees by their rule of thumb and need of the hour. They feel that standard theories of management cannot be applied to all instances and issues in a professional life. At times, the fast paced nature of modern business does not give leverage for standard policies and procedures to be developed and thus followed in a strict manner.
